Validation of Real-World Behavioral Impact

Validate the real-world behavioral impact of constraint-aware sustainable diet recommendations, including long-term adherence, user trust, and potential unintended effects, through online deployment or user-centered studies.

Background

The proposed framework is evaluated only through offline experiments using recipe-rating and interaction data. Consequently, its effects on actual dietary behavior are unresolved: improved sustainability metrics in recommendations do not establish that users will follow the recommendations over time, trust them, or avoid unintended consequences. The paper identifies online deployment and user-centered studies as necessary for evaluating these real-world outcomes.

References

Finally, our evaluation is limited to offline experiments, and the real-world behavioral impact of constraint-aware recommendations, such as long-term adherence, trust, and potential unintended effects, remains to be validated through online deployment or user-centered studies.
